Head-r recursively follows links located at (HTML) Web pages hosted on an HTTP server, and performs HEAD requests upon links of interest to the user. The intended use is to create URI lists for later selective mirroring of file hosting sites.

Flac-utils is a toolkit for managing FLAC files. Its primary usage is syncing metadata between sets of FLAC files. Flac-utils also provides a Python module called flac_compare that can be used separately. The utilitiy consist of three tools: flac-sync, which syncs a file tree of FLAC comments for files with the same audio-part; flac-diff, which compares two FLAC files' metadata information and shows the differences; and flac-add-picture, which adds album cover art to the files using Amazon.

mod_asn is an Apache module that uses BGP routing data to look up the autonomous system (AS) and the network prefix (subnet) which contains a given (client's) IP address. mod_asn is highly scalable. To do lookups in high-speed, it uses the PostgreSQL ip4r datatype, which is indexable with a Patricia Trie algorithm to store network prefixes. This is the most suitable algorithm, being able to search through around 250,000 existing prefixes quickly. mod_asn is usable as a standalone module, and the lookup result can be used by scripts or other Apache modules. For instance, a download redirector could base its decisions on the lookup result provided by mod_asn.

MirrorBrain is a framework to run a content delivery network using mirror servers. It solves a challenge that many popular open source projects face: a flood of download requests, often magnitudes more than a single site could practically handle. A central (and probably the most obvious) part is a "download redirector" that automatically redirects requests from Web browsers or download programs to a mirror server near them. Choosing a suitable mirror for a user's request is the key, and MirrorBrain uses geolocation and global routing data to make a sensible choice and achieve load-balancing for the mirrors at the same time. The algorithm is both sophisticated and easy to control and tune. In addition, MirrorBrain monitors mirrors, scans them for files, generates mirror lists, and more.

scst_qla_isp is an SCST target driver for QLogic
HBAs with the ISP chipset (22xx, 23xx, and 24xx
HBAs). SCST is a mid-level SCSI target subsystem
for Linux, which allows a remote host to access
local storage devices through the SCSI protocol.

iSCSI-SCST is an iSCSI (Internet SCSI) target
implementation on top of SCST, a mid-level SCSI
target subsystem for the Linux kernel. This
software makes it possible for remote systems to
access local storage over any TCP/IP network.

SRPT is a SCSI RDMA Protocol (SRP) target
implementation on top of SCST, a mid-level SCSI
target subsystem for the Linux kernel. This
software makes it possible for remote systems to
access local storage over an InfiniBand network.
This storage protocol target implementation offers
a higher bandwidth and a lower latency than any
other storage protocol target implementation
available for Linux.

SCST is a mid-level SCSI target subsystem for
Linux. This subsystem allows a remote host to
access local storage devices through the SCSI
protocol. SCST supports multiple network storage
protocols, including iSCSI, SRP, and FCoE, and also supports Qlogic 22xx/23xx SCSI HBAs. Strong points of SCST are its stability, maturity, high
performance, and low latency. See also the iSCSI-SCST, SRPT and scstqla2x00t projects, as well as open-fcoe.org.

apub is a tool to simplify uploading documents of
a site to remote servers. Simply create an XML
configuration file containing one or more site
definitions, with the local and remote document
root. After that, you can upload any file in any
of your document roots with one simple command.
